Overview
The QTM750-35.328MBB-T is a surface-mount crystal oscillator (XO) manufactured by QST, operating at a nominal frequency of 35.328 MHz. It utilizes CMOS output logic and requires a 3.3V supply voltage. The device features an enable/disable function for power management and offers a frequency stability of ±50 ppm. It is designed for commercial temperature ranges, specifically operating between -10°C and +70°C. The component is housed in a compact 4-SMD, no-lead package with a maximum supply current of 10 mA.
Feature Summary
- Integrated enable/disable control functionality
- CMOS digital output signal compatibility
- Compact surface-mount package design
Applications
- Consumer electronics timing circuits
- Industrial control system clocks
- Communication equipment synchronization
Procurement Notes
Verify the specific suffix 'BB' against official QST documentation to confirm the exact temperature range and packaging specifications. Ensure that the required operating environment falls within the -10°C to +70°C limit. Confirm supply voltage requirements match the 3.3V specification before integration into the circuit design.
Selection Notes
Select this component when a 35.328 MHz clock source with CMOS output is required for commercial-grade applications. Consider the ±50 ppm stability requirement and the specific -10°C to +70°C operating window. Compare against variants like the MBE series if extended industrial temperature ranges are necessary for the target application.
Part Context
This part belongs to the QST QTM750 series of standard oscillators. It shares the same form factor and electrical interface as other models in the family but differs in frequency and temperature rating. The 'BB' suffix typically denotes specific environmental or packaging attributes distinct from other suffixes like 'MBE'.
Replacement Considerations
Direct substitutes include the QTM750-35.328MBE-T, which offers the same frequency but operates over an extended industrial temperature range (-40°C to +85°C). Verify pin compatibility and thermal performance differences when swapping between these variants.
